The Chair’s Niche:

When I agreed about a year ago to accept the position of chair of biology, it was an easy decision to make.  Biology enjoys the largest number of majors, a relatively stable group of dedicated faculty, a close cadre of motivated and hard-working students, an outstanding faculty and student research program, and connection to three exciting new interdisciplinary programs. Clearly, Chuck Stinemetz had led the department well during his six year term as chair.  Little did any of us know at that time, including him, that he would soon be the Dean of Academic Affairs at Ohio Wesleyan, his alma mater.  Professor Stinemetz left big shoes to fill, both literally and figuratively.  On behalf of the biology faculty and students, I wish to use this public space to acknowledge Dr. Stinemetz’ service and extend our gratitude.  I hope to serve so well.

One might ask what there is left to do.  If my schedule the first part of this semester is any indication, there is plenty.  As examples, we must meet the conflicting challenges of a new foundation curriculum, increased numbers of majors and reduced faculty teaching involvement.  The opening of Barrett Library should eventually lead to expansion and remodeling of the department facilities.  And this year we are hiring four new faculty.  Which brings me to you, the student.  Students are an integral part of our hiring process, so please be on the lookout for calls to participate in meeting with and evaluating faculty candidates.  A department’s strengths are largely a result of the dedication of its students.

Curricular Evolution:

Course Changes and Announcements

Biology and the New Curriculum

The transition to the new Foundations curriculum includes changes in crediting for classes. As courses in all departments throughout the college change from 3 credits to 4 credits, some other crediting changes are happening in Biology. Most upper-level courses with lab will now be listed as 4-credit lecture sections and 1-credit labs. Even though lab and lecture are listed separately for these classes, you still have to take lab and lecture together, just as you always have!

Crediting labs requires that they be listed on Banner separately from the lectures, and that the lab for each course receives its own CRN. When you enter these 4+1 upper-level courses on your tree during pre-registration, the lecture section CRN should be entered, as always, in the A1, B1, or C1 slots on your tree (notice that your upper-level Biology class should be listed first to give you the best chances for getting the one you want). The lab CRNs for the courses on your A, B, and C trees should be entered in Lab tree.

Environmental Science

The requirements for the Environmental Science Minor have changed slightly. Since registration is coming up, talk with Drs. Kesler or Cappellato if you have any questions about what courses to take. For most biology majors, the minor only requires two additional courses you might not think of taking.

Coral Reef Ecology

Coral Reef Ecology is now two, two-hour courses - Biology 253 on campus and Biology 254 in Honduras.  Since admission into this course is by permission only, you must talk with Dr. Kesler before registration if you are interested in gaining admittance to Biology 253.

[pic]

There will be an information session October 27th in FJ-B at 3:45 PM.  Please try to attend if you have any interest in this course.

Upcoming Sabbaticals

May Change Course Offerings in ’07-‘08

During the next academic year (’07-’08), Drs. Mary Miller and Jay Blundon are expected to be gone on sabbatical leaves. We are currently undertaking two searches for 1-year faculty replacements to cover their teaching responsibilities. Our goal is to be able to offer courses in Genetics and Animal Physiology in ’07-’08, but until we complete the hires, we do not know for certain what other upper-level offerings the new faculty may provide. Currently, Dr Miller teaches Microbiology, and Dr. Blundon teaches Neuroscience, but those courses may not be offered in ’07-’08. For students who are considering the Neuroscience major, you are urged to speak to Dr. Blundon now about scheduling, and to consider signing up for his Neuroscience class this spring, especially if you are a junior.

Signals and Displays

(short communications)

TRI-BETA

The Biology Honor Society

Earlier this month, Tri-Beta sponsored student presentations on biology-related summer and semester-abroad activities. The following presenters offer these brief summaries of what they discussed that evening:

Adam Robinson ’07: I was always very interested in studying abroad, but as a biology major also pursuing a health care career, I was a little reluctant to undertake any travel because of the many two-semester courses (organic, physics, etc.) and other various scheduling complications. Yet, by meeting with both academic and study abroad advisors, I was able to select a foreign program that accommodated my undergraduate coursework and left my future career plans uninhibited. My time abroad was an irrevocably valuable experience to my education and my life.

Cianna Pender ’07: I spent most of my summer on independent research. Starting last semester, I found that a river in my hometown held 7 federally threatened or endangered species of freshwater mussels. By calling people associated with Malacology (whom I found on the Internet), I found some very nice and well respected local authorities who gave me guidance during the summer. My research involved 78 quadrat surveys in the Chipola River, in which I determined the abundance of mussels; the genus, species, length, and width of each individual; the substrate composition and other physical factors.  Currently, I am working to find patterns in my data and plan to write a paper.

Christina Campion ’07: I worked for the past two summers at Oak Ridge National Lab (Oak Ridge, TN) studying the effects of global climate change on several tree species. This was sponsored through their HERE (Higher Education Research Experience) program. ORNL cosponsors students with the Department of Energy and UT Knoxville. Stipends and housing are provided for 10 week summer programs as well as fall or spring semesters. For more information, see . Applications are due in February.

William Sheftall ’07: This past summer I worked in Reno, NV for the U.S. Forest Service. I assisted three women working on their PhDs in Botany.  Work consisted of lab duties, as well as field work.  From this experience I gained a better understanding of what is required for a PhD, met some great people, and was able to travel to many places in California.  I learned of this position through Dr. Kesler, who would forward jobs to me that he would find through a list-serv.  If you are interested in a summer job similar to this, ask a professor, whose field you are interested in, if they have any ideas, list-serv connections, or contacts for you

Get Your Work in Print!

After hours of hard work in the lab or field, why not publish your research in the Rhodes Journal of Biological Science? If you’re doing research this year or have a completed project, contact this year’s editor, Ross Hilliard hilrw@rhodes.edu, about submitting your paper.

hello from our

newest Department member

Ms. Kim Stevenson

Ms. Kim Stevenson is a native Memphian who joins us as our new Departmental Assistant. She has a great background for working in the Biology Department, with a BS in Biology from the University of Memphis. At the U of M, Ms. Stevenson’s specialty was Vertebrate Zoology. She also spent several years working in the Blood Banking industry managing a plasma center, and as a Blood Donor Recruiter for St. Jude Children’s Research Hospital. All that is behind her now, so don’t go asking her for donations for your vampire friends around Halloween! Currently, Ms. Stevenson is working on a Master’s degree from the U of M, and when she’s not working she likes to read, and to write horror fiction (well, maybe you can ask her about that blood after all!).

Ms. Stevenson is also an avid traveler who spent two summers in the Czech Republic teaching English as a Foreign Language, and has traveled to Paris and London. Right now she is deciding whether her next destination should be Italy or Amsterdam, so if you have been to either place, stop by and tell her about your highlights. While you’re in the Bio. office, you can also check out the cute picture of Ms. Stevenson’s 3 year old long haired dachshund, Willow. Ms. Stevenson began her working career as a student worker in the Anthropology Department at the U of M. Sixteen years and 4 college departments later, she says, “I am thrilled to be in what I think is the BEST department ever, and I’m looking forward to many more years here.” Please stop by sometime to introduce yourself and to welcome Ms. Stevenson!

St. Jude research program going strong

Applications for next year’s Summer Plus Research Program will be available in late January. Keep a lookout for notices or e-mails informing you of the details. For additional information, contact Dr. Blundon or see

BIOLOGY RESEARCH AWARD

Each spring, the Biology Department honors a student with its Award for Outstanding Student Research in Biology. Any student who has completed research at Rhodes or elsewhere is eligible for this award and cash prize. To be considered, a student must submit a five to seven page research paper, plus a recommendation from the research supervisor. If you are interested in submitting your work for this prize, please speak to your advisor or to Dr. Miller. The deadline for applications for this Research Award will be announced in the spring issue of BIOFEEDBACK.

Biology Seminar News

Don’t forget the upcoming two fall seminars sponsored by the Biology Department. On November 13, Dr. Andrea Duina from Hendrix College will be presenting, “Dysfunctional Relationship: When a Transcription Factor Just Can’t Let Go.” Dr. Duina studies the molecular mechanisms that regulate genes in cells. He specifically has looked at the histones, the proteins that regulate transcription. Earlier this year, Dr. Duina was awarded a $370,654 grant from the National Science Foundation (NSF) to fund his undergraduate research on histones in his lab.

The second seminar is scheduled on December 4. Dr. Terry Hill will present, “Novel Components of Cell Wall Growth in Filamentous Fungi: A Team Approach,” based on research that he has done with Dr. Darlene Loprete in Chemistry and the rest of a big team of Biology, Chemistry and BMB students. Drs. Hill and Loprete were also recipients of an NSF grant to fund their research and undergraduate involvement in their work on fungal genetics and growth. Numerous students have capitalized on this support and the results of their research have appeared in several peer-reviewed journal articles with Drs. Hill and Loprete (see p. 2 for one example).

Biology seminars are scheduled at 4:15 in FJ-B. Refreshments, and an opportunity to meet the speakers, will be available in the Biology Library at 4:00.
